你说的都对.
英语中逗号代替汉语的冒号,也就是说英语中没有冒号,表示人说话时统统用逗号
逗号后首字母不要大写
逗号+and+句子,and不能省,
逗号不能单独连接两个句子,必须有连词
逗号一般出现在长句子中,一般在连接词前,比如说and、but等.
分号一般很少出现.
当你看见有but,and,also,as well as,because,so 等等的字眼时.例句:
I didn't wake up on time this morning so I was late for school.(逗号在 so 前面是可有可无,一般不会写因为第二个句子自己不能独立,不能算完整所以可有可无,只是为原本的句子做注解而已)
当两个句子都是独立时,逗号就一定得在but,and,also,as well as,because,so
等等词后面用上,如:
I didn't wake up on time this morning.
I had a very bad headache.两句都是独立句.加在一起时,逗号必须出现:
I didn't wake up on time this morning,because I had a very bad headache.
如果是用however,therefore,thus,on the other hand诸如此类的,其实是要用 ;
